Answer 1

just press alt + enter in loading and select Create string value resource "loading" and then write the Resource Value of the string, just put in Resource Value: loading

also inside setMessage you can work with a string like this

mProgressDialog.setMessage("Loading...");

but is a good practice to use Strings than hardcodeding strings.

You can follow this images

First alt + enter into loading

Then just write Loading... inside Resource Value

Then you can go to your Strings.xml that is inside res - values and see that yoru String is there
